"10 In the accompanying sheet of drawings which forms a part of this description the fabric is shown on an enlarged scale.

Figure 1 is a plan View of the fabric, the tufts being spaced apart transversely. l5' Fig. 2 is a longitudinalsection through the fabric.

Fig. 3 is a transverse section through the fabric,Y

the tufts being spaced apart.

'Ihe fabric can be woven on an Axminster loom '20 of the type shown in Patent No. 529,636 to Eugene Tymeson, the main cam shaft being geared to make one revolution to each three beats of the loom as shown in my Patent Number 1,964,939; and the heddle cams making one revolution to 25 each six beats of the loom, and effecting six permutations of the heddles.

Commencing with the pile forming yarns of the first row, these are looped under and bound in by a first shot of weft 11. A second shot of 30 weft 12 follows behind this row. A pair of sets of heavily tensioned chain warps 13 and 14 lie respectively over and under these rst and second shots and are then crossed. By reason of heavy tensioning they will be brought more nearly into a straight line and into the same horizontal plane than appears from Fig. 2. A third shot of weft 15 is laid below both of the sets of chain warps and serves as a support for the pile forming yarns. This is held up by binder warps 16 which lie alternately over all of the shots of weft about which the pile forming yarns are looped and under all of the other shots of weft, more particularly under the shot of weft which lies under the loops of the pile forming yarns. In consequence these binder warps pass around the shots of weft at acute angles and the pattern is less concealed at the back. The pile forming yarns 17 of the next row are looped under and bound in by a fourth shot of weft 18, and a fifth shot of weft 19 follows behind this row, and the chain warps 13 and 14 having been crossed, they lie respectively under and over these fourth and fifth shots of weft. A sixth shot of weft 20 is laid below both of the chain warps as in the case of the third shot, serves as a support for the pile forming yarns, and is held up by the binder warps. This completes the permutation and the next shot of weft is like the first and the weave repeats. The tension on the binder warps determines the extent to which the pattern shows on the back. With little tension the pattern will show slightly on the back, with increased tension it shows more clearly. The numerals herein applied to the several shots of weft are for the purposes of identication, and it is not essential that they be made in the order indicated by the numerals in the fabrication of a rug or carpet.

The warp and weft threads crossed under the loops of the pile forming yarns serve as a foundation for their support, and effect a saving in the length necessary for these yarns. As but one warp thread in three and but one weft thread in three lies under the loops the pattern is not hidden on the back. As the fabric is conveniently woven in a needle loom, the weft threads are laid double as shown.

I claim:-

l. A tufted pile fabric comprising rows of pile forming yarns, shots of weft about which the pile forming yarns are looped, shots of weft between each row of pile forming yarns, a pair of sets of chain warps crossed between the rows of pile forming yarns, shots of weft for the support of the pile forming yarns and under the two sets of chain Warps, and a binder warp which lies 85 alternately over all of the shots of weft about which the pile forming yarns are looped and under all of the other shots of weft.

2. A tufted pile fabric comprising rows of pile forming yarns, shots of weft about which the pile forming yarns are looped, shots of weft beu tween each row of pile forming yarns, a pair of sets of heavily tensioned chain warps crosses between the rows of pile forming yarns, shots of weft for the support of the pile forming yarns o5 and under the two sets of chain warps, and a binder warp which lies alternately over all of the shots of weft about which the pile forming yarns are looped and under all of the other shots of weft.

3. A tufted pile fabric comprising rows of pile forming yarns, shots of weft about which the pile forming yarns are looped, shots of weft between each row of pile forming yarns, a pair of sets of chain warps which alternately overlie two shots of weft one being a shot of weft about which the pile forming yarns are looped and the other being a shot of weft between the rows of pile forming yarns, shots of weft for the support of the pile forming yarns and under the two sets of about which the pile forming yarns are looped and the other being a shot of weft between the rows of pile forming yarns, shots of weft for the support of the pile forming yarns and under the two sets of chain warps, and a binder warp which lies alternately over all of the shots of weft about which the pile forming yarns are looped and under all of the other shots of weft.
